how do u tune for a top swap on a 97? You cant run a 97 gtp file, tranny doesnt want to get out of second. You cant run a gt file cant control the supercharger settings. Is there a way to splice the two types of files together?

PCM doesn't control the SC. The boost bypass is mechanically controlled. Your PCM problems with the GTP and tranny is because the PCM thinks you have 2.94 gearing where the GT has 3.29. I would think that if you have access to a tuner you can change the gear settings in the PCM to know your running 3.29s not 2.94s.

we changed the gear ratio settings but its not engaging the 3rd gear solenoid. i know the pcm doesnt "control" the SC. sorry if i mistyped that but there are settings in a gtp file that you can modify which the gt doesnt have...

PM chico on what he did when he pressurized his ride.

Who is doing your tuning for you?

Flash a GTP file to your GT PCM and add the GT tranny settings to it.

Corey thats what we did and it still did not work. there seems to be a hidden setting that cant be changed

Thats exactly what i did with mine. Make sure you got all of the settings flashed on there.

Double check all of your wiring, something might be pinched. Check under the battery, there is a tranny wire that gets pinched a lot, just make sure all of the wires are out from underneath the battery

everything runs fine when the gt file is flashed in.. remember i have the wonderful 97 with the 60 tran a 97 gtp has the 65.

upload your gt file again ... add more fueling, and add timing, curently i just got a new tune the other day and i have a gtp tune on my pcm ....

thats what im running right now so that i can have my gears back.. it sucked driving 90 miles on the hw in second... my turner is checking into things to find out whats up, i just want my car to run right and i want boost. and i thought all the hard work was behind me....

no! dont add any timing. retard it!!! i cant stress that enough. GT's have much more timing than GTP's for a reason. and dont mess with the fueling, just use GTP settings for fueling if youre running L67 injectors

Yah something isn't hooked up right, you have a 97 and missing something, or there isn't something correct in the tune bin file.

well i dont have any way to change it back now

i dont know i just want my belt on and be able to run fine.... its getting so stressful and the guy lives 2hrs away....

Not you, theone.

A GT with a top swap and increased timing is asking for trouble.
